NAILING MACHINE.

Application led December This invention relates to nailing machines and is herein exemplified in a machine for nailing heels Vupon shoes, although the field of'utility of the invention is not limited to machines for performing this particular nailing operation. A

lIn the copending application of Joseph H. Pope, Serial No. 612,254, filed January 12, 1923, there is disclosed and claimed an improved nailing die which actual use in `shoe manufacture has shown to 'possess marked advantages over devices formerly used for similar purposes. It is the object of the present invention further to develop the invention of the said application, with a view to increasing the facility with which a nailing machine in which it is incorporated may be accommodated to work of different sizes or work requiring different nailings. Y i i For the accomplishment of the above stated object the invention provides, in combination with a gang of vnail drivers the nail yengaging ends ofvwhichkare movable into a plurality of different nailing patterns, a carrier provided with a plurality of different, vnail driver controlling, pattern elements and movable, independently ofthe nail drivers, to place any selected one of pattern elements in coi-operative relation to the drivers. By. incorporatingja series of driver controlling pattern elements in the organization of the machine and `making provision for their ready and'selective interchangeability the Vchange in the setting of the machine necessary to change it from one nailing to anotheris made possible of accomplishment in a few seconds, a period of time so brief as to have .practically no retarding e'ect upon the production of work by the machine.

In the illustrative Yembodiment ofthe invention herein shown, the movable carrier consists of a rotary, turret in which the driver guiding pattern elements are formed or mounted, the axis of rotation of the said turret Vbeing so located that any one of the pattern members, each of which is shown as comprising' a. set of guide holes, may be readily moved into guiding vrelation to the nail drivers.

Preferably, there is combined with each pattern element a heel holder so constructed and related tothe pattern element as to locate and hold a heel having nail holes ar- 11, 1925. Serial No. 74,753.

vto the position to bring the proper pattern element and heel holder into `co-operative relation to Ythe nail drivers.

Further details of the invention andthe advantages derived from its use will be understood and appreciated from reading the following detailed description of one practical embodiment thereof, in connection with y the accompanying drawings; in which-- Figure 1 is a view, in front elevation, of a portion of a heel attaching machine embodying the invention; Fig. 2 isa vertical II, II of Fig. 1; and Y c Fig. 3 is a plan view of the mechanism shown in Figs. 1 and 2.

Referring now to the drawings, 10 indicates a die block havingprojecting tongues v12 at its sides by which it is supported in the guides provided for that purpose in the frame'14 of a heeling machine which m-ay 'be of the same general type of construction as that disclosed in the prior patent to J. H. Pope, No. 1,431,980, dated October 17, 1922, to which reference may be had for a more complete disclosure of the details of the heeling machine structure which are not illustrated in the present drawings."

The die block is chambered to provide an open space 16 extending entirely through it and a group of driver guiding tubes 18, supported by ball'and socket mountings 20 is located within the space 16; The mountings of the guide tubes 18 are arranged to register with the nail drivers 22 so that when the drivers are lowered each driver shall enter its corresponding guide.

The mountings 20 of the guides 18 permit the nozzle ends of the guides to be swung into-various positions, to produce different nailing patterns, and the drivers 22 are suf-L iiciently resilient to follow the ideflected guides easily. The construction so far de-A scribed is, or may be, substantially like that disclosed in the Pope application identified above. Y

In order to control thev movement of the drivers into different vpredetermined nailing patterns, a plurality of different pat- Vsection on the line tern elements 2l are provided. As shown, each of these pattern elements comprises a plate 26 provided with a series of tapered holes 28, the centers of which are arranged inl the pattern of a desired nailing. lt will be understood that the nozzle ends ot the guide tubes 18, entering the holes 28, are thereby positioned in accordance with the nailing pattern which it is desired to produce.

The pattern plates 26 are mounted in, and may or may not be integral with, a turret 30 whichA is easily retatable about a gournal 32, the axis of which` is-vertical. rlhe upper end ot the journal- 32. is non-circular, as shown at 34, and issupported to slide vertically in a stationary bea-ring 36, a flange 38 at the upper end ot the non-c1rcular section 3l serving to limit downward movement of the journal by engaging the top of thebearing.

rhe turret 30 isl provided with a. sleeve 40 which lits rotatably upon the journal? 32 and a nut 42, threaded upon the lower end of. the journal, retains the turret thereon. A pin ille, threaded through the stationary earing- 36 and projecting in the path. ot rotation o the turret, is arranged to. enter any one of series ot holes 4l6-in the up` per tace of the turret. There is one hole 4:6v torI each patternr member 24EY and the holes and pattern members are so related that when the turret is locked in a given position` by the pin il engaging in al hole the correspondingpatterni member is delinitely located in nailing position, as may beclearly seen from Fig. 2. The turret 30' may be lowered, to d-isenegage it from the locking pin lll, and for this` purpose the journal Y32 is provided with a depending portion i8 in which is mounted a pin 50;. Flhev pin- 50 is engaged by the forked end ofvr a' lever arm 52 movable about. a stationary pivot 5,4: by means oiza handle 56. A spring58, acting` upon the handle 56, tends tof lteep the turret elevated, in engagement withv the loclr.- ing pin 4A# but when the handle 56 is drawn outward the turret. is depressed, disengaged from thel locking`= pin, and may be easily rotated to place any selected one of the pattern members 26' in driver controlling` position, whereupon the handle is released, allowing the turret to riseI and be lockedI by the pin l-lf.

Secured to the under sideot each: pattern element 26. is a heel holder. 60 arranged' to locate and holdi a heel having nailV holes arranged to correspond'` to the holes 28. in said pattern element. ln Fig. 2' a rubber heel 6 .f is shown in: oneY of the heel holders 60,. with a shoe 645 tov whichz'the heel' is to be attached supported on a jack 66' and properlypositioned in relation to thefheel bv an adjustable gage 68. u

Indicati'ngf marks, such as are shown. at

70, may be placed upon the periphery ol the turret as an aid to the operator in determining instantly which pattern element and heel holder unit is in operative position. ally bear identifying numbers, and the indicating` marl; 7() may convenientlybe the saine as those upon 'the heel for which the corresponding pattern element and heel holder unit is designed.

The holes or openings 28 are suificiently tier-ed -or tapered so that the guide tubes 18 automatically nd their positions when the turret is elevated after it hasbeen depressed to permit a desired pat-tern controlling and heel holding unit to be placed inl oper.- ative relation to the drivers, and the range ot angular movement ot the-guide tubes is, or may be such that a complete, ordinary range oit sizes and nailings may be covered with one set of guides. ln the illustrated machine, tor example, provision is made for eleven different sizes and nailings without the necessity ot detaching any part of the machine and replacing it by another.

Having described the invention, what is claimed as new and desiredtof be secured by Letters Patent is Y 1. ln a nailing machine,xthe combination ot a o'l' nail drivers the nail engaging ends ot whichv arev movable into ai plurality ot different nailing patterns', and a carrier provided with aA plurality of diffterent, nail driver' controlling, patternelements, said carrier ybeing movable independently of the nail drivers to place any se.- lectedv one ot' said pattern elements incooperative relation to said drivers.

2'. ln a nailingvmachine, the combinaition ot a of nail drivers the nail" engagingends et which are movable. intoI a plurality ot different nailingpatterns', a corresponding ot adjustable driver guides bv which the drivers are guided into said different patterns, and a carrier pro vided with a: plurality o different pattern elements each ot said pattern elements being engageable by the gang of' driver guides to locate the guides according to one nailing pattern, said carrienbeing` movable independently of the driver guides to place any selected one of said pattern elements in positionV to be engaged by said driver guides. 8. ln a nailing machine, the combination ot a gang of nail drivers, and a rotary turret having a plurality of sets of differently arranged guide holes therethrough, said turret being movable to place any one et said sets ot guide holes in guiding relation to the drivers. f

4f. In a heel nailing machine, the'combinai tion ot a gang ot nail drivers, anda carrier provided with a plurality ot different, nail driver controlling, patternl elements and with an equa-lf plurality of heel. holders,

The rubber heels of commerce usudrivers to coincide With the nail holes in said heel, said carrier being movable yto place any one of said pattern elements and its associated heel holder in co-operative 10 relation to said drivers.

In testimony whereof I have signed my lname to this specification.
